Shuttle/pass combo - how to designate which shuttle line?

I purchased the $399 shuttle/festival pass combo.
There was no place to indicate which shuttle line I wanted, only a place to buy additional shuttle passes.
Friend had the same issue come up so I'm sure it happened to lots of others.
What to do?

Edit: Answered below (combos are for Tennis Garden line but can be switched)

* GA/Shuttle combo - Allows entrance into the venue, parking lots & camping areas and comes with a shuttle pass to the venue from the Tennis Garden. You will be able to change shuttle lines at a later date through the end of December 2012.
$399 Domestic (+ additional charge for international shipping)

Yeah, this happened to me, so I cancelled my order - I had to wait longer - then bought a pass & then shuttle. Front gate sux.

Wknd 2 this year, my cousin bought my & his passes/shuttle, and he called Frontgate to switch from Tennis Garden to JW Marriott. They said we were all good & sent him a confirmation email. When he got the passes they were still Tennis Garden so he called again & they said on Friday we could use them at the Marriott stop to ride over to the Polo Fields and we had to exchange them when we got there. That's exactly what happened. The exchange tent was right there in the shuttle lot & took less than 5 mins. Shuttles have prolly been the smoothest thing ever at Coachella.
